用there be句型改two books are in the backpack

I have two books on the desk.(用there be 句型改写) （ ）（ ）two book on the desk.急用, 用there be句型改two books are in the backpack there be 句型怎样改写成一般过去时? 用There be 句型, There are two books on the table(用two books作主语改为to be句型) There be句型谓语单数还是复数 是不是采用就近原则?如：there is a book and two pencils here. there are two pencils and a book here. 这两句话都对是吗? 谢谢啊 there be 句型改一般过去时some要改any吗? There be句型There __ a book,two pens and some rulers on the desk.应该填is还是 are?为什么呢? There are a book and two pens on the desk .There be 句型中可用语法一致原则,上面的句子应该是正确的 英语翻译用there be 句型 英语翻译用there be 句型 英语翻译用there be 句型 用there be句型造句 英语翻译用 There be...句型 要求用there be句型 There are two apple and three pears on the plate.(用to be句型改写) two loaves of bread换成there be句型用is还是are 用there be 句型改写I have two pens and a backpack on the desk.
